“It’s over/Yeah, we’re through/So I’m-a unfriend you,” sings Greyson Chance on Hold on ‘Til the Night, his reedy voice rising in a fit of pique. Though Chance may be serious about committing the ultimate social-media diss, the 13-year-old is anything but threatening on this potential blockbuster of a debut. The Oklahoma native scored big with a solo piano cover of Lady Gaga’s “Paparazzi” (41 million YouTube views and counting), and here he’s always in a lather, singing power ballads about holding on to dreams and seizing the day. His handlers clearly hope he’s the next Bieber; sadly, there’s not an ounce of fun in him. Unfriend.
